Y y andhas for its object the provision of ya novel attachment tolgo 'on already existing., plows without necessitating any changes 1n the structure thereof, `it being Consequently to produce the machiney atrlesscost than if all the parts had to be built in the first place.

' gaan important object is the provision of a mm/e1 machine 'of this character having ai novel n arrangement and mountingl of' the means which carries the ground engaging f wheels, the purpose beingtlo yavoid side draft and. prevent binding ofhany ofthe parts when turning corners orvmaking turnsas for Ainstanceat the ends of rows. `V y Another Objectis to provide a device of I this characte1"liavinga pluralityof Inova-bly Y mounted furrow vopenings provided vwith `le-.Y l

Referring more particularly to the drawuings, the letter A designates a portion of a plow frame to which the invention is applied. In carrying out the invention, I pro- 5 vide a frame structure designated generally by the numeral 10, which structure may in n clude any desired number of longitudinally extending bars 11 bolted or otherwise secured at 12 to the plow frame A as clearly indicated. Secured to therouter side of each of the longitudinal frame members 11 is a bar AAn additional object is to aideviceAvr l of this character which will Vbecomparative-y Figure 3 is a cross section taken onthe` f f YCHARLas a'Banni-'orMmilvlvvinnnfoaneoif 'er @mammaireharing a`liiojiermv'aanyY i .curved forward `portion14:serving `as supporting means fora transverselyarranged shaft .or rod f 11,5 ongfwhich are pivoted the Y lforked i :`orward. ends-1.16z ofv rearwardlyjexe tending ydownwardly Y inclined .arm members ;It vis intended, that the-depthoff penetration by means of l thesedfurrow-openings Vwhichmcarries crankarms 21` with whichare pivotally i connected at 22, depending rods '23 porting meansfor thedisks' 18 .sothatt e lattery may Ibe Lraised or lowered, as `the lcase may be.

Secured to and forming part o-f the frame Y 11 and extending transversely with respect thereto are hollow axle members 29 terminating at their outer ends in U-shaped members 30 withwhich `are pivotally connected, yat 31, similar U-shaped members 32 on the forward ends of rearwardly and downward-l ly inclined arms 33 upon the lower ends of which are journaled ground engaging wheels 34. Mounted Vabove the frame 10 onk suitable brackets'35 is a hopp-er 36 for` the grain or otherl seed tollOe planted this hopper having* 160 i its top open and normally closed by a removable cover 37 whereby access may be had to the interior for refilling purposes.- This hopper maybe provided with any suitable4 dropping mechanism, not shown, op-erated by a shaft 38 driven by means of ak `gear 39 meshing with a suitablegear on a shaft 10 journaled through the hollowaxlemembersr29. The axle members 29 are suitably mountedbelow the end portions of the hopv perand eachv contains a shaft 40. Journaled through the yhub, portions of the arm members A33 are stub shafts 11A andy one thereof should-be varied and for this reason l have -provided upstanding,4 bearing members 19 mount-eden thev rear ends of. the members 13 i n andvserving as a support for arockjshaft 20 i v 'by aehan 43 ywhich is in turn engaged aboutv In the operation, it

carries a sprocket ,42 periphera-lly engaged a sprocket 44fcarried by one of the ground engaging wheels 3ftd Located within thel U- shaped members 30" and 3Q is a shortsection 4,5 of shaftinghaving universal jointy connec-` tions'46 with the stub axle members 41 and with the shaft 40.

will be readily apparent that when the machine is drawn along o any suitable dropping boot 47 may be provided for receiving the seeds discharged from the hopper and conducting them to the furrowsformed by the ydisks A18. -When making turns or rounding corners,'it is' clear that the: arms 33 carrying the ground engaging wheels 34 may swing freely upon the "axle members Q9, the provision ofthe shaft sections and universal joints connecting the same permittingk corresponding movement of the drive shafting without binding and without necessitating *throwing out the operating mechanism atL any time. lIt is Vtherefore clear that thedeviee may make .turns at 'the ends of' rows or may follow uneven rows or travel in -a curved pathwith- 'out'interfering with the Vseed droppingaction, it being therefore obvious that there '5 willbe no unplanted areas such as occurs f Furthermore, ample means has been prowhen the ordinarytype of seed drill is used.

vided for raising and'loweringthe furrow i. openers for regulating the depth o'fpenetra-` vtion and'consequently the depth of the furrows, depending upon the nature of the seeds planted; Itis really believed that the construction, operation and advantages will be readily apparent to one skilled inthe art without further'V explanation.

While I have shown 'and described the preferred embodiment of the invention, it

' should be understoodthat I reserve the right to make such changesin the form, construction and arrangementof parts aswill not 'l depart from the 'spirit'of they invention Vor the scope vof the subjoined claim.

Having thus described 'the invenaai In a drill attachment for a plow including ing a hollow axle mounted below the end of lthe hopper'and extending longitudinally thereof and terminating at its outer end 'in a U-shaped member, a hollow shaft having a U-shaped portion pivotally connected with said iirst named U-shaped member, an arm on the hollow shaft carrying a ground engaging wheel, a shaft j ournaled through'` the hollowY axle, al shaft journaled through the hollow shaft, vaflink pivotally connectingk both of said last named shafts within the confines of said U-shaped member and the U-shap'ed'V portion whereby to define a universal joint connection, -a drive devicercar-V Va frame, and a hopper, drive means compriscoY ried by the ground engaging wheel, and a `V drive device' carried yby the secondfnamed shaft and operatively connected with the first named drive device. f' CHARLES A.
